ABSTRACT
This study aimed to elucidate the incidence and characteristics of neurotoxicity in patients receiving methotrexate (MTX) treatment. A retrospective analysis was performed using data from the electronic cohort database spanning from January 1990 to December 2021. This review focused on patients who manifested neurotoxic symptoms post-MTX therapy, excluding patients with peripheral neuropathy. Of the 498 individuals who received MTX, 26 (5.22%) exhibited neurotoxicity. Pediatric patients (< 18 years) accounted for 18 cases (7.44%), whereas adults (> 18 years) comprised eight cases (3.13%). The median onset age was 11 years (range 4-15) in the pediatric cohort and 39.5 years (range 19-67) in the adult cohort. A predominant male predisposition was noted (21 patients, 80.77%). The majority of patients (21, 80.77%) experienced neurotoxic effects following multiple MTX administrations. Modes of MTX delivery included intrathecal (37.0%), intravenous (22.2%), and combined routes (40.7%). Clinical presentations were predominantly encephalopathy (69.2%), followed by encephalomyelopathy (15.4%), myelopathy (11.5%), and polyradiculopathy (3.8%). Fourteen patients recovered (53.85%). Risk factors were male sex, pediatric age (particularly above 10 years), and administration route (intrathecal in adults and intravenous in pediatrics). Although infrequent, MTX-related neurotoxicity has a substantial impact on patient prognosis, with potential development following even a single dose. Its radiological resemblance to diverse neuropathologies, such as cerebral infarction and subacute combined degeneration, necessitates vigilant diagnostic scrutiny.

BACKGROUND: Cesarean scar pregnancy is a complicated and potentially life-threatening type of ectopic pregnancy. There is no gold standard for its management. The aim is to demonstrate the efficacy and safety of treatment by hysteroscopic tissue removal system after systemic methotrexate injection. METHODS: We report the case of a 27-year-old patient who had previously had a C-section and who presented herself to the emergency room with pelvic pain and metrorrhagia. The human chorionic gonadotrophin (hCG) serum level was positive. The exploration revealed an ectopic pregnancy on the cesarean scar. She benefited of 4 systemic injections of methotrexate. As the hCG became negative, endovaginal ultrasound confirmed the avascular nature of the mass. Surgical resection by mechanical morcellation hysteroscopy (TruClear™) was performed under general anaesthesia, visual control and ultrasound guidance. RESULTS: This procedure was successful. It was an ambulatory procedure and there were neither intra- nor postoperative complications. CONCLUSIONS: To our knowledge, this is the first time in Belgium that a hysteroscopic tissue removal system procedure has been used to treat a caesarean scar pregnancy. This technique seems to be safe for both the patient and the surgeon and could become a new approach for cesarean scar pregnancy management.
CONTEXTE: La grossesse sur cicatrice de césarienne est définie comme la présence d'un sac gestationnel dans une isthmocèle créée par une hystérotomie préalable. Il n'existe pas de gold standard concernant sa prise en charge. L'objectif est de démontrer l'efficacité et la sécurité du traitement par résection mécanique hystéroscopique des tissus après injection systémique de méthotrexate. Méthodes : Nous rapportons le cas d'une patiente de 27 ans ayant déjà eu une césarienne et qui s'est présentée aux urgences avec des douleurs pelviennes et des métrorragies. L'exploration révèle une grossesse sur la cicatrice de césarienne. Elle a bénéficié de 4 injections systémiques de méthotrexate. La résection des résidus trophoblastiques avasculaires a été réalisée par voie hystéroscopique en utilisant l'hystéroscope par action mécanique de type -TruClear™ et ce, sous contrôle échographique concomitant. Résultats : Cette procédure ambulatoire effectuée sous anesthésie générale a été un succès. Il n'y a eu aucune complication per- ou postopératoire. CONCLUSIONS: À notre connaissance, c'est la première fois qu'une résection par action mécanique des résidus trophoblastiques sur cicatrice de césarienne est réalisée en Belgique. Cette technique semble sûre pour la patiente et le chirurgien et pourrait devenir une nouvelle approche pour la prise en charge d'une grossesse sur cicatrice de césarienne.

The incidence of ectopic pregnancy (EP) has increased in recent years, owing to causes such as pelvic inflammatory diseases and assisted reproductive technologies (ART). The present study reported a case of a 33-year-old nulliparous woman with a history of previous ectopic pregnancies, who underwent pelvic ultrasound in August 2022, which revealed a double EP including a cervical pregnancy and a tubal stump pregnancy. Despite known risk factors and elevated beta-human chorionic gonadotropin (ß-hCG) levels, a conservative approach, utilizing multiple doses of systemic methotrexate (MTX) injections, was employed to preserve fertility at the Regional Perinatal Center in Aktobe, Kazakhstan. Treatment efficacy was monitored through ß-hCG levels and ultrasound imaging, with successful resolution of both EPs and preservation of reproductive function. The present case highlighted the safety and efficacy of MTX therapy in managing complex EP presentations, emphasizing the necessity of individualized treatment approaches in reproductive medicine, particularly in terms of preserving fertility in patients undergoing ART. Multiple high doses of MTX injections were beneficial for pregnancy with two distinct regions, fetal cardiac activity, and elevated serum ß-hCG level. Further research is required to explore optimal treatment strategies for EP, considering patient-specific factors and treatment goals.

Methotrexate is a critical component of curative chemotherapy for pediatric acute lymphoblastic leukemia (ALL), but is associated with neurotoxicity. Information on long-term outcomes following an acute neurotoxic event is limited. Therefore, this report compares neurocognitive performance more than 12 months post diagnosis (mean = 4 years) between ALL patients with (n = 25) and without (n = 146) a history of acute neurotoxicity. Compared to children with no documented on-treatment neurotoxic event, children who experienced a neurotoxic event during treatment exhibited poorer performance on measures of fine motor function (p = .02) and attention (p = .02). Children with ALL who experience acute neurotoxicity may be candidates for early neuropsychological screening and intervention.

INTRODUCTION: Severe cutaneous adverse reactions (SCARs) arising from drug interactions can carry life-threatening implications and result in lasting effects. SCARs can be triggered by various factors, with trimethoprim/sulfamethoxazole identified as a primary culprit. Anticonvulsants and antineoplastic agents have been noted as secondary triggers. Notably, antineoplastics linked to SCARs include immunomodulatory agents. The higher mortality rates among cancer patients with SCARs underscore the significance of comprehending cancer--specific risk factors. Our objective is to present the case of a boy with acute lymphocytic leukemia (ALL) who developed Stevens-Johnson syndrome (SJS) following MTX treatment. CASE REPORT: We present the case of a three-year-old male patient diagnosed with ALL who developed Stevens-Johnson syndrome (SJS) subsequent to the administration of MTX, following the "BFM 2009" protocol. He had undergone intrathecal MTX administration on six previous occasions. Our patient received IVIG at a dose of 2g/kg along with steroids, resulting in partial clinical improvement after 21 days. An innovative protocol was developed, involving IVIG before MTX infusion and dexamethasone before MTXi, with folinic acid rescue. Intravenous immunoglobulin (IVIG) mitigates SJS/TEN via type IV hypersensitivity down-regulation and apoptosis curbing. CONCLUSION: As far as we know, the prophylactic use of IVIG to counteract SCARs in a pediatric leukemia patient represents uncharted territory. Moreover, research into the immune system dynamics within these patients and the preservation of indispensable treatments should involve allergist-immunologists as part of the multidisciplinary team attending to neoplastic conditions.

Background and Objectives: Anti-tumor necrosis factor-alpha (TNF-α) agents are effective in treating rheumatoid arthritis (RA) but may entail a risk of lymphoma due to TNF-α's role in immune surveillance. This systematic review and meta-analysis assesses the risk of lymphoma in patients with RA treated with anti-TNF agents versus patients treated with methotrexate and/or a placebo. Materials and Methods: The Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Embase, PubMed, and Google Scholar were systematically searched for relevant literature. Data were extracted and analyzed to determine risk ratios (RRs) and 95% confidence intervals (CIs), with heterogeneity assessed using I2 statistics. Methodological quality and risk of bias were assessed using the Cochrane Risk of Bias tool for randomized controlled trials (RCTs) and the Newcastle-Ottawa Scale for observational studies. Results: The search yielded 932 articles, 13 of which were retained for qualitative review and 12 for quantitative synthesis. Overall, the studies reviewed included 181,735 participants: 3772 from six RCTs and 177,963 from seven observational studies. The meta-analysis of RCTs revealed no significant difference in the risk of lymphoma between patients receiving anti-TNF-α therapy and patients on conventional treatments, with an overall RR of 1.43 (95% CI: 0.32-5.16) and I2 of 0%. Conversely, observational studies showed some variability, with an overall RR of 1.43 (95% CI: 0.59-3.47) and significant heterogeneity (I2 = 95%), whereas others indicated a potentially elevated risk of lymphoma in specific subgroups but had inconsistent results. Conclusions: The systematic and meta-analysis revealed no significant difference in the risk of lymphoma for patients with RA treated with anti-TNF-α agents versus conventional therapies. However, given the limitations of the studies included, additional research is needed to validate the results and explore potential risk factors contributing to the development of lymphoma in patients with RA.

PURPOSE: This study examines the risk of severe oral mucositis (SOM) in graft-versus-host disease prophylaxis (GVHD) compared to other agents in hematopoietic cell transplantation patients. METHODS: A comprehensive search of four databases, including PubMed, Embassy, Web of Science, and Scopus, was conducted to identify studies reporting frequency and severity of oral mucositis in association with GVHD prophylactic regimens. RevMan 5.4 was used to perform the meta-analysis. Risk of bias assessment was carried out using the Rob-2 tool for randomized clinical trials (RCTs) and ROBINS-I tool for observational studies. RESULTS: Twenty-five papers, including 11 RCTs and 14 observational studies, met the inclusion criteria. The pooled results from eight RCTs showed a higher risk of SOM in patients receiving MTX or MTX-inclusive GVHD prophylaxis versus non-MTX alternatives (RR = 1.50, 95% CI [1.20, 1.87], I2 = 36%, P = 0.0003). Mycophenolate mofetil (MMF) and post-transplant cyclophosphamide (Pt-Cy) consistently showed lower risk of mucositis than MTX. Folinic acid (FA) rescue and mini-dosing of MTX were associated with reduced oral mucositis severity. CONCLUSION: Patients receiving MTX have a higher SOM risk compared to other approaches to prevent GVHD, which should be considered in patient care. When appropriate, MMF, FA, and a mini-dose of MTX may be an alternative that is associated with less SOM. This work also underlines the scarcity of RCTs on MTX interventions to provide the best evidence-based recommendations.

The short-term use of glucocorticoids (GCs) in combination with methotrexate was recommended for the initial treatment of rheumatoid arthritis by the European League Against Rheumatism. A randomized controlled trial (GLORIA) showed that treatment of older patients with low-dose GCs in combination with disease-modifying anti-rheumatic drugs was more efficacious than disease-modifying anti-rheumatic drugs plus placebo in terms of disease activity control and prevention of joint destruction. Glucocorticoid-related adverse events were likely to increase relative to placebo, with no increase in serious adverse events and fractures over 2 years. Observational studies showed an increased risk of serious infections, cardiovascular events, and fractures associated with long-term continuation of GCs in older patients, but the adverse events may be associated not only with GC toxicity but also with poor disease control of rheumatoid arthritis. In the GLORIA study, low-dose GCs during 2 years could be tapered off safely, but many patients had a flare of disease activity after discontinuation of GCs. In the two representative large Japanese registries (IORRA and NinJa), the proportion of patients using GCs and non-tumor necrosis factor inhibitors increased with increasing age at disease onset, with a decreasing trend in methotrexate use. The proportion of patients in remission with GC treatment also increased with increasing age at onset. These suggested that it is not easy to discontinue GCs in older patients. If GCs cannot be terminated in the short term, it may be acceptable to use GCs to control disease activity for up to 2 years.

BACKGROUND: Hepatotoxicity associated with methotrexate (MTX) is mainly due to disruption of redox balance and development of oxidative injury to hepatocytes. Melatonin (MLT) is a potent antioxidant and regulates wide range of biological functions, processes and utilized as adjuvant for number of medical applications. The current study investigated the mitigating effect of MLT on the MTX-induced hepatotoxicity. METHODS AND RESULTS: Adult male rats received MLT (25 mg/kg, orally) for seven days flowed by single injection of MTX (20 mg/kg, ip) then treat with MLT continued for additional 7 days. The present result showed MLT treatment mitigated histopathological changes in the liver that associated with normalization of ALT and AST activity as well as bilirubin, albumin and alfa-fetoprotein levels in serum of MLT + MTX-treated rat to comparable control level. MLT treatment significantly reduced MDA content and myeloperoxidase activity while enhanced the activity of superoxide dismutase, catalase and glutathione content in the liver indicating the empowerment of the antioxidant status. Amelioration of MLT-induced oxidative stress resulted in a reduction in the inflammatory response due to antioxidant restoration and inhibited apoptosis indicated by downregulation of caspase-3 expression. The replenishment of antioxidant content powers the defense system of the hepatocytes. As a result, apoptosis is reduced which might be due to the ability of MLT protect DNA integrity thus maintaining hepatocyte functions and structure. Consequently, liver histology was protected. CONCLUSIONS: In summary, MLT modulates liver function and structure by orchestrating linked processes, including redox balance, inflammatory response, suppression of caspase-3, and DNA damage.

OBJECTIVES: To compare the risk of cardiovascular events among Janus kinase inhibitors (JAKIs), biological disease-modifying antirheumatic drugs (bDMARDs) (tumour necrosis factor inhibitors (TNFIs) and non-TNFIs) and methotrexate (MTX) in Japanese patients with rheumatoid arthritis (RA). METHODS: Using Japanese claims data, patients with RA were enrolled in this study if they had at least one ICD-10 code (M05 or M06), were new users of JAKIs, bDMARDs or MTX between July 2013 and July 2020 and being 18 years old or older. The incidence rate (IR), IR ratio and adjusted hazard ratio (aHR (95% CI)) of cardiovascular events including venous thromboembolism, arterial thrombosis, acute myocardial infarction and stroke were calculated. A time-dependent Cox regression model adjusted for patient characteristics at baseline was used to calculate aHR. RESULTS: In 53 448 cases, IRs/1000 patient-years of the overall cardiovascular events were 10.1, 6.8, 5.4, 9.1 and 11.3 under the treatments with JAKIs, bDMARDs, TNFIs, non-TNFIs and MTX, respectively. The adjusted HRs of JAKIs for overall cardiovascular events were 1.7 (1.1 to 2.5) versus TNFIs without MTX and 1.7 (1.1 to 2.7) versus TNFIs with MTX. CONCLUSIONS: Among patients with RA, individuals using JAKIs had a significantly higher risk of overall cardiovascular events than TNFIs users, which was attributed to the difference in the risk between JAKIs and TNFIs versus MTX. These data should be interpreted with caution because of the limitations associated with the claims database.

We report an autochthonous case of mild unifocal chronic pulmonary paracoccidioidomycosis in a 48-year-old previously healthy woman with no history of possible environmental exposures in endemic rural areas, supposedly resulting from reactivation of a latent pulmonary focus secondary to the use of methotrexate for the control of Chikungunya arthropathy. Laboratory investigation ruled out other immunosuppression. Her only symptoms were a dry cough and chest pain. Diagnosis confirmed by needle lung biopsy. There were no abnormalities on physical examination nor evidence of central nervous system involvement. MRI of the total abdomen showed no involvement of other organs. Computed chest tomography showed a favorable evolution under the use of itraconazole (200 mg/day). Different tomographic presentations findings are highlighted when performed before and after treatment. CONCLUSIONS: PCM should be considered even in a woman without a history of consistent environmental exposure and in a non-endemic geographic area.

OBJECTIVE: Risk minimisation measures (RMM) are put in place to ensure safe and effective use of medicines. This study assessed whether RMM for five medicines are implemented in Dutch clinical guidelines. DESIGN: Descriptive study. METHOD: Dutch clinical guidelines where treatment with valproate, fluoroquinolones, methotrexate, metformin or fluorouracil was recommended were identified. In those guidelines that had been updated after publication of the RMM, we determined whether RMM-information was included in the guideline. RESULTS: Out of 50 identified guidelines recommending treatment with one of the five medicines, only 21 (42%) were revised after RMM-implementation. Of these 21 guidelines, 12 (n = 57%) included RMM-related information. CONCLUSION: Uptake of RMM information in Dutch clinical guidelines is limited and RMM-publication does not prompt guideline updates. This suggests that guidelines alone are not an optimal way to inform health care professionals of new safety warnings.

The intricate immune mechanisms governing mucosal healing following intestinal damage induced by cytotoxic drugs remain poorly understood. The goal of this study was to investigate the role of lymphotoxin beta receptor (LTßR) signaling in chemotherapy-induced intestinal damage. LTßR deficient mice exhibited heightened body weight loss, exacerbated intestinal pathology, increased proinflammatory cytokine expression, reduced IL-22 expression, and proliferation of intestinal epithelial cells following methotrexate (MTX) treatment. Furthermore, LTßR-/-IL-22-/- mice succumbed to MTX treatment, suggesting that LTßR- and IL-22- dependent pathways jointly promote mucosal repair. Although both LTßR ligands LIGHT and LTß were upregulated in the intestine early after MTX treatment, LIGHT-/- mice, but not LTß-/- mice, displayed exacerbated disease. Further, we revealed the critical role of T cells in mucosal repair as T cell-deficient mice failed to upregulate intestinal LIGHT expression and exhibited increased body weight loss and intestinal pathology. Analysis of mice with conditional inactivation of LTßR revealed that LTßR signaling in intestinal epithelial cells, but not in Lgr5+ intestinal stem cells, macrophages or dendritic cells was critical for mucosal repair. Furthermore, inactivation of the non-canonical NF-kB pathway member RelB in intestinal epithelial cells promoted MTX-induced disease. Based on these results, we propose a model wherein LIGHT produced by T cells activates LTßR-RelB signaling in intestinal epithelial cells to facilitate mucosal repair following chemotherapy treatment.

Psoriasis might bring about an increased risk of liver diseases like nonalcoholic fatty liver disease and fibrosis. The impact of methotrexate on liver function is still a cause for concern, because of the studies suggesting an increased risk of liver damage and others finding no association. The focus of this study was the liver functions in psoriatic patients investigating the impact of long-term use of methotrexate on liver in psoriasis. A retrospective investigation including 140 patients with psoriasis receiving methotrexate treatment for at least 6 months and a control group consisted of 105 healthy ones was conducted. Liver function tests (AST, ALT, PLT) were assessed, and the association of baseline PASI with FIB-4 and APRI values was investigated. Additionally, FIB-4 and APRI values at baseline, 3rd, and 6th months of methotrexate treatment for psoriasis were compared. Compared with the controls, psoriatic patients exhibited significantly higher FIB-4 scores (p = 0.004). A moderate and significant correlation was observed between baseline PASI score and baseline FIB-4 score in psoriatic patients (p < 0.001, rho = 0.626). Long-term methotrexate use had no effect on APRI or FIB-4 (p = 0.104 and p = 0.475, respectively). Psoriatic patients face an elevated risk of liver fibrosis. Long-term methotrexate use does not adversely affect liver function in psoriatic patients. Noninvasive tools like APRI and FIB-4 scores can be employed to evaluate the risk of liver disease in these patients.

OBJECTIVES: To assess the safety and efficacy of upadacitinib versus adalimumab from SELECT-COMPARE over 5 years. METHODS: Patients with rheumatoid arthritis and inadequate response to methotrexate were randomised to receive upadacitinib 15 mg once daily, placebo or adalimumab 40 mg every other week, all with concomitant methotrexate. By week 26, patients with insufficient response to randomised treatment were rescued; patients remaining on placebo switched to upadacitinib. Patients completing the 48-week double-blind period could enter a long-term extension. Safety and efficacy were assessed through week 264, with radiographic progression analysed through week 192. Safety was assessed by treatment-emergent adverse events (TEAEs). Efficacy was analysed by randomised group (non-responder imputation (NRI)) or treatment sequence (as observed). RESULTS: Rates of TEAEs were generally similar with upadacitinib versus adalimumab, although numerically higher rates of herpes zoster, lymphopenia, creatine phosphokinase elevation, hepatic disorder and non-melanoma skin cancer were reported with upadacitinib. Numerically greater proportions of patients randomised to upadacitinib versus adalimumab achieved clinical responses (NRI); Clinical Disease Activity Index remission (≤2.8) and Disease Activity Score based on C reactive protein <2.6 were achieved by 24.6% vs 18.7% (nominal p=0.042) and 31.8% vs 23.2% (nominal p=0.006), respectively. Radiographic progression was numerically lower with continuous upadacitinib versus adalimumab at week 192. CONCLUSION: The safety profile of upadacitinib through 5 years was consistent with the known safety profile of upadacitinib, with no new safety risks. Clinical responses were numerically higher with upadacitinib versus adalimumab at 5 years. Upadacitinib demonstrates a favourable benefit-risk profile for long-term rheumatoid arthritis treatment.

Background: A woman in her seventies presented to the accident and emergency department (A&E) with shortness of breath that had increased over a period of three weeks. She had a history of COPD, hypertension and polymyalgia rheumatica. A medication error involving methotrexate, used for autoimmune diseases, was discovered during her medical history review. Case presentation: The patient arrived with stable vital signs, including 94 % oxygen saturation and a respiratory rate of 20 breaths/min. She had been taking 2.5 mg of methotrexate daily for the past three weeks instead of the prescribed weekly dose of 15 mg. Other examinations revealed no alarming findings, except for a slightly elevated D-dimer level. Interpretation: Considering her medical history and exclusion of other differential diagnoses, methotrexate toxicity was suspected. The patient was admitted to the hospital and intravenous folinic acid was initiated as an antidote treatment. Five days later, the patient was discharged with an improvement in the shortness of breath. This case underscores the importance of effective communication in health care, particularly in complex cases like this, where understanding dosages and administration is crucial. Medical history, clinical examinations and medication reviews, often involving clinical pharmacists, are vital in the A&E to reveal medication errors.

OBJECTIVES: Non-adherence to rheumatoid arthritis (RA) treatments must be identified. A methotrexate (MTX) urinary dosage (METU) was recently developed. The aim of our study was to assess adherence to MTX in RA using METU in real-life conditions and to compare it with indirect adherence measurement technics. METHODS: We performed a cross-sectional study at Reims University Hospital. We included over 18-year-old patients with RA treated by MTX for more than 6 months. Patients were invited to complete demographic, clinical and psychological questionnaires and adherence measurement technics (Compliance Questionnaire of Rheumatology (CQR) and Medication Possession Ratio (MPR)). A urinary sample was collected to measure MTX and information about tolerance was evaluated through Methotrexate Intolerance Severity Score. RESULTS: 84 patients were included, 26 using oral MTX, 58 subcutaneous (SC) MTX. Among them, 73% were female, mean age was 61.5 years, MTX mean dose was 15 mg/week and 61.9% were treated by biological DMARDs (Disease Modifying Antirheumatic Drugs). 77 patients (91.7%) were adherent to treatment according to METU, whereas MPR and CQR reported less adherence (69.5% and 61.9%, respectively). MPR and METU were not significantly different in SC MTX users (p=0.059). Non-adherent patients had a higher number of tender joints and C reactive protein value (p<0.05). CONCLUSION: This is the first largest study evaluating MTX adherence in patients with RA using a urinary dosage. We identified that indirect adherence measurements did not reflect real-life adherence. It would be appreciable to realise METU, in a new study, in patients with RA with unexplained response to treatment, to consider it before escalating therapeutic strategy.

BACKGROUND: Several studies of multi-drug regimens for osteosarcoma have shown different efficacies and are still controversial. Meanwhile, chemotherapy options have remained largely unchanged over a couple of decades. This study is designed to ascertain the outcome and safety of Methotrexate, Doxorubicin, and Cisplatin regimen for chemotherapy in osteosarcoma patients through the utilization of meta-analysis. METHODS: We interrogated trials that compared the MAP regimen with other regimens as chemotherapy for osteosarcoma from several databases encompassing PubMed, Science Direct, and grey literature (Google Scholar) until December 2022. The analyzed outcomes including Event-Free Survival (EFS), Overall Survival (OS), Tumor Necrosis (TN) rate, and Adverse Event (AE) were then analyzed using RevMan 5.4 software in fixed or random effect models. RESULTS: Our meta-analysis comprised 8 prospective articles that evaluated a cumulative number of 2920 OS patients. The analysis results indicated no meaningful difference in 5-year EFS (OR=0.99, 95% CI=0.77-1.27, [P = 0.91]) and neoadjuvant chemotherapy response (TN) (OR=0.76, 95% CI=0.49-1.17, [P = 0.22]) between the MAP and control groups. Furthermore, 5-year OS analysis revealed a significant association in the control group (OR=0.82, 95% CI=0.68-0.99, [P = 0.04]). However, the control group was associated with statistically meaningful AE compared to the MAP group, particularly in thrombocytopenia (OR=0.46, 95% CI=0.23-0.90, [P = 0.02]) and fever (OR=0.34, 95% CI=0.26-0.46, [P < 0.00001]). CONCLUSION: The present meta-analysis showed that the MAP regimen remains preferable in treating osteosarcoma patients despite no significant outcome compared to the other regimens considering the less frequent AE in the MAP regimen.

Methotrexate (MTX), although an indispensable part of contemporary treatment protocols for childhood acute lymphoblastic leukaemia (ALL)/lymphomas (LBL) in improving outcomes, can lead to serious neurotoxicity with long-term consequences. The aetiopathogenesis, predisposing factors and treatment for MTX-induced neurotoxicity are not yet well defined. The aim of our study was to detect the incidence, risk factors and to assess the overall outcomes of MTX-induced neurotoxicity among large cohort of paediatric ALL/LBL patients treated on a uniform protocol. We conducted retrospective audit of medical records of 622 consecutive children (≤14 years) diagnosed with ALL and LBL between January 2018 and December 2022 and treated on modified BFM-95 protocol at the Department of Pediatric Oncology, Regional Cancer Centre, Thiruvananthapuram. Risk factors predisposing to MTX-induced neurotoxicity were identified using binary logistic regression analysis. Forty-three children were diagnosed with MTX-induced neurotoxicity with an incidence rate of 6.9%. More than two-thirds of them had high-grade MTX-induced neurotoxicity CTCAE v5.0 with a median age of 9 years (range: 9 months to 14 years). Almost half of them developed MTX neurotoxicity during Protocol M followed by Phase-Ib consolidation (15%). Majority of these patients (84%, 36/43) were challenged again with MTX, with 11% (4/36) developing recurrence. Fifteen per cent had persistent neurological deficits at last follow-up. Univariate analysis found older age (age > 5 years) (p < 0.001), T-cell phenotype (p = 0.040), tumour lysis syndrome during induction (p < 0.001), baseline renal problems prior to MTX exposure (p < 0.001) and CNS leukaemic involvement (p < 0.003) to be significantly associated with MTX neurotoxicity. On multivariate analysis, older age (>5 years), tumour lysis during induction and CNS leukaemia retained statistical significance (p < 0.05). Methotrexate-induced neurotoxicity during paediatric acute lymphoblastic leukaemia/lymphoma therapy is a transient phenomenon in majority and re-challenge with MTX is generally safe. Older age children who develop tumour lysis during induction and CNS leukaemic involvement are at increased risk for MTX-induced neurotoxicity during ALL/LBL treatment.
